Letters Patent No. 92,272', lated July 6, 18369.`

HEARTH-PLATE FOR COOKINGeSTOVES.

.The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'lt may concern Be it known that I, DAVID B. Cox, of Troy,in the -county of Rensselaer, and State of New York, have invented anImproved Hearth-Plate for Cooking- Stores; and I do hereby declare thatthe following is -a fully and exact description thereof', referencebeing had to the accompanying drawings, making part ot' this`speciication- I Figure l being a vertical section, from the frontbackward, of so much of a cooking-stove as is necessary to show myinvention.

Figure 2, a transverse vertical section through the hearth.- s

Figure 3, a perspective view of a cooking-stove, hav-y ing the improvedhearth-plate.

Like letters designate corresponding parts iu all of the figures.l

My invention consists in a raised hearth-plate, A,

termed a supplement-al hearth-plate, since-it adds to the-capacity ofthe sunk hearth beneath, and sup plies defects therein heretoforeexperienced.

The plate is turned down at the edges a a., in the form of propermouldings, so as to raise the main central portion l) considerablyhigher than the edges of the hearth B, which is, or may be, formed asusual.

The raised part is' plain or dat, and the entire plate covers the wholeof the hearth, except the mouldings d d at the edges, so that themouldings of the plate j form a continuation of the ornamentation of'the hearth, Y

making a handsome finish, and adding lmaterially to the'good appearanceof the stove.

But the essential advantage of this raised hearth-y plate consists inthe greatly-increased dept-h given to the ash-chamber, so that a muchdeeper ash-pan may` be used. n

Another advantage is, that the concave form of the hearth-plate rendersit less liable to warp out of shape in casting.

There may be a register, f, in the top or middle of the hearth-plate,andthe raised plate affords addi' tional room beneath for theintroduction ofthe draught through the hearth. Y

'I do not claim a cover, or closed chamber, situated' to the hearth of acooking-stove, substantially as and for the purposes herein specied.

' DAVID B. COX.
